[PHP-DB] Images on-fly
Hallo People,
I have one problem with creating images on-fly.
Therefore I created 2 files:
1. resize_image.php with the following
?php
if (!$max_width)
$max_width = 150;
if (!$max_height)
$max_height = 100;
$size = GetImageSize($image);
$width = $size[0];
$height = $size[1];
$x_ratio = $max_width / $width;
$y_ratio = $max_height / $height;
if ( ($width = $max_width) ($height = $max_height) ) {
$tn_width = $width;
$tn_height = $height;
}
else if (($x_ratio * $height) $max_height) {
$tn_height = ceil($x_ratio * $height);
$tn_width = $max_width;
}
else {
$tn_width = ceil($y_ratio * $width);
$tn_height = $max_height;
}
$src = ImageCreateFromJpeg($image);
$dst = ImageCreate($tn_width,$tn_height);
ImageCopyResized($dst, $src, 0, 0, 0, 0,
$tn_width,$tn_height,$width,$height);
header(Content-type: image/jpeg);
ImageJpeg($dst, null, -1);
ImageDestroy($src);
ImageDestroy($dst);
?
AND
2. filex.php .In that file i read from database where the image is stored en
then i show small images(thumbnails).
thet part of the code is :
?php do { ?
tr
td width=156 height=32 valign=top?php echo
$row_rsSubGroup['name']; ?/td
td colspan=2 valign=top?php
$fotolink=../dbtest/.$row_rsSubGroup['image_1']);
echo IMG
SRC=\resize_image.php?image=$fotolink\;
?
/td
/tr
?php } while ($row_rsSubGroup = mysql_fetch_assoc($rsSubGroup)); ?
This doesn't WORK. Please HELP.

[PHP-DB] selecting a constant or label in php
Sorry for another newbie question, I'm learning. In Sybase I can do: select COMM_REGIONID , count(1) from COMM_REGIONID where PHYSICAL_ID is null select COMM_TKGRP , count(1) from COMM_TKGRP where PHYSICAL_ID is null I get parsing errors when putting it in this: $result = sybase_query(select COMM_REGIONID , count(1) from COMM_REGIONID where PHYSICAL_ID is null select COMM_TKGRP , count(1) from COMM_TKGRP where PHYSICAL_ID is null , $server_sybase); How can I hardcode COMM_REGIONID and COMM_TRKGRP? _ Wonder if the latest virus has gotten to your computer?

RE: [PHP-DB] selecting a constant or label in php
COMM_REGIONID and COMM_TRKGRP are not columns in the tables. They are the actual table names. I want the count of the PHYSICAL_ID where it is NULL. I need to do this for multiple table so I want to hardcode the tablename and then have the count: --- COMM_TKGRP0 COMM_REGIONID 0 using COMM_REGIONID, 'COMM_REGIONID' and \COMM_REGIONID\ all fail with: Warning: sybase_query() [http://www.php.net/function.sybase-query]: Sybase: Server message: COMM_REGIONID not found. Specify owner.objectname or use sp_help to check whether the object exists (sp_help may produce lots of output). It's not found because it's not a column. I just want it in there so when I insert it into another table I will know which count applies to which table. Everything I try, gets an error. Sorry, I should have mentioned what COMM_REGIONID was first.

[PHP-DB] calculations using variables in html table cell
I am generating html tables dynamically. Each table has multiple columns and various calculations need to be done on each column and displayed at the bottom of the column. I am including the code from one table below. The $tablerow generates the table data and the $tablefooter generates the rows at the bottom that will include the calculated values. Preceding the $tablerow declaration, I have declared some variables and done calculations. I then included these in the $tablefooter to display the calculated values. This works fine. However, I have many other calculations on other columns in other tables. Using this method, I would have to declare many new variables just for calculations. I am wondering if there is a way to do these calculations directly in the table cells. I am pretty new to PHP and have not used calculations much. $sumpop += $POP; $sumadultcirc += $ADULTCIRC; $sumjuvcirc += $JUVCIRC; $tablerow[1] = trtd . $row[name] . /td . td$POPtd$ADULTCIRC/td td$JUVCIRC/tdtd$TOTCIRC/tdtd$CIRCPERCAP/tdtd$TOTREF/tdtd$R EFPERCAP/td/tr; $tablefooter[1] = trtdbTable total/b/tdtdb$sumpop/b/td tdb$sumadultcirc/b/tdtdb$sumjuvcirc/b/tdtdb$TOTCIRC/b /td tdb$CIRCPERCAP/b/tdtdb$TOTREF/b/tdtdb$refpercap/b/td /tr trtdbTable average or per capita/b/tdtdb$POPAV/b/td tdb$ADCIRCAV/b/tdtdb$JUDCIRCAV/b/tdtdb$TOTCIRCAV/b/td tdb$CIRCPERAV/btdb$TOTREFAV/btdb$REPERAV/b/td/tr; -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] calculations using variables in html table cell
If you have to build complex, dynamic tables, do yourself a favour and use a class that will allow you to feed directly arrays of numbers. I use PEAR HTML_Table, which is great and easy to use. You will have recouped the investment of learning the class after about one hour.

I think you want to replace if $tel == $dbrows with if ($tel ==
$dbrows).

[PHP-DB] Addslashes
hi all, i'm really buffled by what i got and would appreciate any help possible! although i addslashes and stripslashes, i still get a backslash ( \ ) character infront of a single inverted comma ( ' ) and also whenever an amberscend ( ) appears... please help! thanx thanx.. for example: in my form (form.php), i have something like that: input type=text name=field1 value=? if ($form[field1]) echo stripslashes($form[field1]); ? upon submitting the form, the verification file (verify.php) will be executed, and it has lines like that: ? session_register(form); foreach($_POST as $varname = $value) $form[$varname] = addslashes(trim(EscapeShellCmd($value))); ? ... and then i'll check for the validity of field1. if there is an error, the user will be redirected back to form.php with the value that the user entered echoed with a stripslash. if there is no error, the whole script runs well, but if the user has to be brought back to form.php, it'll print backslashes infront of characters like ( ) ' etc.. also, instead of having a blank text field, i have a text field with contents retrieved from the database.. the database data does not have the slashes and when the first time they appear on the screen, there is no slashes attached too.. the problem is always when the user has an error and needs to be brought back to form.php that the slashes appear and the number of slashes doubles everytime the user has to be brought back to form.php. i have my magic_quotes_gpc set to ON in my phpinfo() and my version of php is 4.1.2. thank you soo soo much!! look forward to your replies. hwee
[PHP-DB] Re: Addslashes
It's the magic quotes setting. Try setting magic_quote_gpc to off. Also, try turning magic_quotes_runtime off.
